METAL WHEEL.

Application led November 1 To all whom t may concern:

Be it known that I, MAURICE a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Metal Wheels, of which the following is a specification.

My invention relates to the construction and method of manufacturing metal wheels with the spoke and hub or rim parts integral.

The object of my invention is to utilize rolled metal bars in the manufacture of wheels and more particularly forms of bar which may be rolled with flanges at or near the edges thereof respectively.

`As an example of the form of bar utilizable in carrying out my invention I have shown a channel bar.

The invention consists essentially in constructing the wheel from a section or 4length or bar the two edges of which are bent to cause the flanges to serve as the rim part of the wheel while the web c." kbase of the bar between the edges is subdivided to form two sets of spokes integrally united in the hub structure.

The invention consists essentially in constructing the wheel from a length of bar having flanges projecting from one face thereof, the base or body being utilized as to one portion in the structure of the hub or rim and as to another part or portion of said base or body is divided to form spokes,vwhile the flanges or ribs are employed in either portion of the wheel, to wit: either the rim or hub. If the floor or base be provided with flanges, projecting therefrom at its edges and from itsintermediate portion as well, the latter, as will be hereinafter described, may be utilized in the rim or hub structure. The channel bar illustrated is shown as rovided with such intermediate flanges or ribs but, as will beobvious to those skilled in the art from the subjoined description, the invention is capable of being carried out by using a bar having flanges or ribs at or near its edges only.

channel bar suitable for use in carrying out my 1nvent1on.

Fig. 9 is a side elevation of a wheel made bar showing from the subdivided blank shown in Fig. 8.l

Fig. l() is a cross-section on the line 10--10 Fig. 9. l

Referring to Fig. 1,-the channel bar is shown with four ribs or flanges two of which indicated at l are at or near the edges thereof while two others, lil, extend from an intermediate portion of t e base or body of the bar and are located respectively at opposite sides of a portion 2 of said base or body which is utilized as the barrel of the hub. The remaining portions 2 are utilized in the formation of the spoke portion of the wheel. .l

The channel bar is preferably a rolled channel bar, a suitable section or length of which, to form preferably the whole wheel, is taken and subdivided. on the lines 3 as indicated in Fig. 2, which lines of division extend from ortion 2 of the bar outwardl in opposite directions, to the edges thereo includin the flanges or ribs 1. When a channel bar having, the intermediate flanges or ribs 1 is employed, and portion 2 is utilized in the hub, said lines of division preferably include also the ilanges 1 and when required by the height of flanges 1, said flanges are also cut away in the sections or parts 4 (see Fig. 3), to accommodate the blank to the operationof bending the section 2 to the circumference of the hub barrel.

The section or length of channel bar having been subdivided as shown, portions 2 are bent up as indicated in Fig. 4 to cause them to assume the relation of spokes to the part 2 in the finished structure and to bring the flanges 1 into the relation of rim to said spokes, said flanges or spoke terminals ordinarily forming, however, a means. for /support and attachment of a separate `rim 5 such as indicated lin Figs. 5 and 6, said rim being attached by welding or otherwise to the spoke ends 1. The portion 2 of the bar is bent in any suitable way to the circumference of the hub barrel, thereby causing sections 1 to meet and form the ends of the box hub while the divisions 2 integral with .said hub are caused to radiate therefrom as spokes, *to whose rim ends formed by flanges or ribs 1 the supplemental rim proper 5 is secured.

Obviously the flanges 1 may be omitted, the flanges l'being retained and the part 2 be utilized or merged in the hub structure in any desired way, as well understood in the art.

Obviously likewise the flanges 1 may be omitted and the flanges 1 retained, the

spokes 2 being connected in the rim in any desired way.

In the channel bar, Fig. 7, the intermediate flanges 1 instead of projecting from the same side of the bar as flanges 1, project from the opposite side and the bar extends slightly beyond the location of the flanges 1. In this modification of my invention the portion 2 of the channel bar is utilized toform the continuous rim instead of the continuous hub, but the sections of 2 are utilized as before in forming the spoke portion of the wheel and the flanges 1, 'instead of being used as a portion of the rim are used as a portion of the hub. In this instance the portions of the body between the flanges 1 andthe extreme edge of the channel bar may be utilized to form the ends of the hub box.

To prepare the channel bar for use it is subdivided as to portion 2 and flange 1 as indicated in the plan view Fig.,8, the lines of subdivision starting from or at the flanges 1.or fr om the two sides of the portion 2 utilized 1n the rim, In addition parts are removed as indicatedy at the spaces 7 to allow portion 1 to come together as a spoke member or disk of the wheel when the part 2 is bent to the circumference of the rim, the parts 2"- at the time of bending being arranged to project from the part 2 transversely. Preparatory to the bending operation the bar having been subdivided as indicated in Fig. 8, the parts 2 to either Side Of `or parts 2 also brings the flanges 1 into the relation indicated in 111g. 10 and brings the portions of the bar exterior to the flanges 1 into position shown, so that they may constitute, in conjunction with the flanges 1, the ends and circumference of the box hub as plainly shown in Figs. 9 and 10. The assembling of them and the disposition of the parts 2 in the relation of spokes to the completed structure is brought about in the operation of bending the part 2 to the vcircumference of the rim. The edges of the flanges 1 where they meet in the hub may be welded together if desired. Also, as will be obvious, the portions of the base of the channel bar beyond the flanges 1 might ybe omitted. Also, as will be obvious, the

flanges 1 might be omitted although it isdesirable to use the same in order to give an overhang to the rim.

The specific form of wheel and method of construction illustrated in Figs. 7 to 10 inclusive is not herein specifically claimed but will form the subject of specific claimsin an application for patent to be filed as a division of the present application.
